Abstract
Cognitive radio technology necessitates accurate and timely sensing of primary users´ activity on the chosen set of channels. Reduction of sensing error may be accomplished through random selection in which idle and active channels are assigned different probabilities of being selected for sensing. The paper presents a probabilistic analysis of this policy and investigates the range of values in which such, incomplete sensing is capable of maintaining an accurate view of the status of the working channel set.
